I do limited spey casting in the salt but mainly to setup overhead casts on my two hand overhead rods.
As you PNP is a great place to fish for migrating coho and you are sure to have a blast come august.
There are a few of us out there waving long rods but only a handful. Mattzoid on this fourm is another guy who fishes two handers off the beach. I am sure he will chime in soon.
